ANALISIS ESTIMASI BIAYA MENGGUNAKAN METODE COST SIGNIFICANT MODEL PADA PROYEK PEKERJAAN JALAN DI KOTA TASIKMALAYA

Abstrak

In the early stages of construction project planning, namely the initial cost estimate to complete a job according to the requirements or contract. Related to budget limitations, the Tasikmalaya City government needs to be wise in using the development budget which results in the need for effective use of funding sources. For this reason, the purpose of this study is to obtain a construction cost estimation model for road works in Tasikmalaya City using the Cost Significant Model method and to determine the level of accuracy of the resulting model.This study uses a quantitative method assisted by the SPSS (Statistical Product and Service Solution) computer program to obtain a statistical approach (regression analysis). By using data from 8 road work samples with the 2021 and 2022 work budget years which are standardized to 2024 using inflation rate data from the Tasikmalaya City BPS.The results of the study showed that the results of statistical testing obtained components of work that significantly affect the total cost are Wearing Layer Laston Work (AC-WC) (X15), Cement Concrete Pavement Work (PPC) (X10), Intermediate Layer Laston (AC-BC) (X12), Class A Cement Aggregate Foundation Layer (Cement Treated Base = CTB) (X8). And obtained the form of a multiple linear regression equation model Y '= -82.806 + 0.974 (X15) + 2.064 (X10) + (-2.378) (X12) + 7.133 (X8).

The accuracy of the project cost estimation model of the 8 (eight) road work packages in Tasikmalaya City using the Cost Significant Model method against the realization of this cost is at the level of class 2 accuracy with a maximum accuracy result of 9.49% and a minimum of -13.96%. according to AACE International.
